VEHiCLE-SEATQ SPECIFICATION forming part of Letters Patent No. 286,178,dated October 9, 1883.

Application filed April 24,1883. (No model.)

To all whom, it may concern.-

Be it known that I, FRANK A. COMSTOOK, a citizen of the United States,residing at Golumbus, in the county of Franklin and State of Ohio, haveinvented a certain new and useful Improvement in Vehicle-Seats, of whichthe following is a full, clear, and exact description, reference beinghad' to the accompanying drawings, forming part of this specification.

Figure 1 represents a plan view of my improved seat. Fig. 2 represents aside View, partly in section. Fig. 3 represents a section of the back,with the sheath before it is rolled around the flange. Fig. 4 representsthe same as Fig. 3, with the sheath rolled down tight. Fig. 5 representsa modified form of the flange and sheath.

The class of metallic seats to which my improvement relates have theback and sides constructed either of a single piece of sheet metal orseveral pieces properly jointed, and are provided with a lower flangefor attach ing the back and sides to the sill of the seat, also with anupper flange for stiffening and strengthening it. Usually a flat ironfillet is used to supplement the flange in strengthening the back andsides.

My improvement consists in substituting for the fillet a wire andsheet-metal sheath or cap, by which means Imake alighter, cheaper, and,in some respects, a better seat, and am enabled to use much of the sheetmetal which would otherwise be lost.

A is the sill of the seat, usually of wood; I), the back and sides, of1sheet metal; E, the lower flange, by which the back and sides are boltedto the sill. B is the wire, rolled into the edge of the upper flange; O,the sheath or The seat back and sides may be made, in the usual form, ofa single piece of metal, or of several pieces jointed together, and,instead of a plain upper flange, I roll a Wire in the outer edge of theflange of any suitable size, as

shown at B in Fig. 2. This of itself serves to strengthen and stiffenthe seat; but in addition I cover the flange and wire with a V- shapedsheath or cap, (shown at (1,) em bracing the wire and fillet. The lowerarm of this sheath 0 extends flush against the back of the seat. Theupper arm, 0, is alittle longer than the lower. The whole flange and capare then carefully and firmly rolled or stamped together, as shown inFig. 4, and the longer arm 0 is bent down to make a smooth strong cornerat the upper edge of the seat, and also to firmly hold the sheath on theseat. In addition to this rolling, bolts may be used passing through theflange and both arms of the sheath. The wire rolled into the edge of theflange and embraced by the sheath gives strength and stiffness to theseat and a beaded edge to the flange, making a more durable and ahandsomer seat, as well as a cheaper one.

In Fig. 5 I show a modified form, where the lower arm of the sheath isshorter, and is only long enough to extend round and embrace the wire,which is rolled in the edge of the flange.

I am aware that seats with the back and sides formed of sheet metal areold, and I do not claim that as my invention; but,

Having fully described my invention, I claim and desire to secure byLetters Patent A vehicleseat having the back and sides formed of sheetmetal, with an upper flange,

the outer edge of whichis rolled round a wire,

and the wire and flange embraced by a V- shaped sheath or cap, the upperarm of which is made long enough to bend down over the upper corner ofthe seat-back, so as to form a smooth corner and hold the sheath inplace without the use of bolts or rivets.
